A newborn sleeps 14–17 hours a day, but never more than 2–4 hours at a stretch. That means many wake-ups for the whole family.
The first weeks aren't about strict routines. They're about understanding your baby's sleep patterns and laying the groundwork for good sleep habits that last.
How newborns sleep in the first weeks
Newborns have a completely different sleep pattern than older babies and adults. According to the AAP, most newborns sleep 14–17 hours per day, spread across many short periods.
| Age | Sleep per day | Longest sleep period |
|---|---|---|
| 0–6 weeks | 14–17 hours | 2–4 hours |
| 6–12 weeks | 15–16 hours | 3–5 hours |
| 3–6 months | 12–15 hours | 5–6 hours |
A newborn's sleep cycles last only 45–60 minutes. Half of that sleep is active (REM sleep), which means plenty of movement, sounds, and brief wake-ups.
Frequent wake-ups are biologically normal for newborns. Baby needs to feed often and hasn't yet developed a circadian rhythm. This is not something you're doing wrong.
The difference between day and night
Newborns don't distinguish between day and night in the first weeks. The circadian rhythm develops gradually from around 6–8 weeks of age, and is usually established by 3–4 months.
You can help your baby learn the difference:
Daytime
- Keep the room bright and airy
- Let normal everyday sounds be in the background
- Talk, sing, and make eye contact
- Daytime naps don't need to happen in a completely dark room
Evening and night
- Dim the lights 30–60 minutes before bedtime
- Use a night light for diaper changes and feedings
- Speak quietly and calmly
- Avoid play and stimulation
- Skip diaper changes unless there's a bowel movement
From around 3 months of age, baby begins to produce melatonin, which regulates feelings of tiredness. That's when consistent bedtime routines start to make sense.
When can you start a sleep routine?
Many parents wonder when they can start with a set routine. The answer: not too early.
0–6 weeks: Focus on getting to know your baby. Notice patterns, but don't try to control them. Baby needs food and closeness on demand.
6–8 weeks: Now you can introduce a simple bedtime routine. Short, predictable steps repeated each evening give baby a sense of security.
3–6 months: The routine can expand and become more established. Baby is ready for clearer structure around bedtime.
Newborns under 6 weeks should not be put on set schedules. They need food and comfort on demand. Trying to "train" a newborn to sleep longer can interfere with food intake and weight gain.
Step-by-step bedtime routine
A bedtime routine doesn't need to be complicated. What matters is predictability — that the steps happen in the same order every evening.
1. Bath or wash (5–10 minutes)
A warm bath is relaxing for most babies. Water temperature should be around 98°F (37°C). Not all babies need a daily bath — a thorough wash works just as well.
2. Massage and dressing (5 minutes)
Apply lotion and put on a clean diaper and sleep sack. Slow, firm strokes on arms and legs are soothing.
3. Nursing or bottle
Feeding right before bed ensures baby is full and content. Dim lighting keeps baby in sleep mode.
4. Sleep sack and dark room
Place baby in a sleep sack (not a blanket) in their own sleep space. Draw the curtains. A room temperature between 61–68°F (16–20°C) is recommended by the AAP.
5. Lullaby or white noise
A gentle song, humming, or white noise signals that it's time for sleep. Repeat the same song each evening to build recognition.
Your pediatrician's office offers regular check-ups from birth through early childhood. Use them actively — your pediatrician can give personalized guidance on sleep routines tailored to your baby.
Wake windows for newborns
A wake window is the amount of time baby can comfortably stay awake between sleep periods. If baby stays awake too long, they become overtired — and then it's harder to fall asleep.
| Age | Wake window |
|---|---|
| 0–4 weeks | 45–60 minutes |
| 4–8 weeks | 60–75 minutes |
| 8–12 weeks | 75–90 minutes |
| 3–4 months | 90–120 minutes |
For newborns, these windows are surprisingly short. A 2-week-old may need to sleep again just 45 minutes after waking.

Sleep cues to watch for
Baby gives clear signals when they're tired. Catching these early makes the bedtime situation much easier.
Early cues (put baby down now!)
- Yawning
- Rubbing eyes
- Looking away from you or from toys
- Becoming quieter and calmer
- Pulling at an ear
Late cues (baby is already overtired)
- Crying and fussiness
- Body stiffening
- Arching back
- Difficult to soothe
The goal is to put baby down when you see the early cues. An overtired baby has a harder time falling asleep and sleeps for shorter periods.
Learn more about reading your baby's sleep cues in our guide to sleep signals.
Common mistakes parents make
Waiting too long to put baby down
The most common problem is going past the wake window. A baby who has been awake too long produces stress hormones (cortisol) that make it harder to fall asleep.
Too much stimulation before bed
Active play, bright lights, and screen use right before bedtime work against sleepiness. Wind down activity 30 minutes before the routine starts.
Comparing with other babies
Every baby is different. The fact that another baby slept 6 hours straight from week 4 says nothing about your baby. The range of normal is enormous.
Switching methods too quickly
Give a new routine at least 1–2 weeks before deciding whether it's working. Babies need time to adjust to changes.
Ignoring your own needs
Parental sleep deprivation affects patience and the ability to read baby's cues. Take turns with your partner, sleep when baby sleeps, and ask for help.
Use the Sleep Tracker to log your baby's sleep and see patterns over time. Many parents discover that baby is sleeping more than they think — it just doesn't feel that way in the middle of the night.
Frequently asked questions
When will baby sleep through the night?
Most babies can manage 5–6 hours in a stretch around 3–6 months of age. "Sleeping through the night" (8+ hours) often doesn't come until after 6 months. Some babies take longer, and that's completely normal.
Should I let a newborn cry it out?
No. Newborns need immediate response and comfort. The AAP recommends being present and giving baby security. Sleep training is not recommended for children under 6 months.
Baby only wants to sleep on me — what do I do?
This is common and natural in the first weeks. Try a gradual transfer: wait until baby is in deep sleep (limp body, calm breathing) before putting them down. Skin-to-skin contact is wonderful, but baby should sleep safely on their back in their own sleep space at night.
Should I wake baby for feeds at night?
Healthy babies with good weight gain generally don't need to be woken, according to the AAP. Premature babies or babies with low weight gain may need waking — check with your pediatrician.
What do I do about sleep regression?
Around 4, 8, and 12 months, many babies experience sleep regression — a period of worse sleep. Stick to the routine, offer extra comfort, and wait it out. Read our guide to sleep regression for more information.
Start sleep tracking today
Understanding your baby's sleep patterns is the first step toward better nights. With the Babysential Sleep Tracker, you can log sleep, see wake windows, and discover patterns you'd otherwise miss.
Many parents find that simply tracking sleep gives them a sense of control — even in the toughest nights.
